To all whom 'it may concern.'

Be it known that I, HARRY E. DE. VAUGHN, a citizen of the United States,residing at Morgantown, in the county of Monongalia and State of WestVirginia, have invented new and useful Improvements in Glass- Furnaces,of which the following is a specification, f

This invention is an improved furnace of the type employed to maintainglass in a molten condition during the usual drawing operations.

It is well known that in the operation of glass furnaces, the piersbuilt up from the bottom of the tank or furnace, or from the wallsthereof, to support the cap of the furnace, and to Separate the drawingchambers, are frequently destroyed by the molten glass. Aside from theloss entailed by the necessity of discontinuing operation of thefurnace, until new piers can be constructed, after the destruction of anQld pier, as stated, the quality of the molten glass is also affected byreason of the absorption by the molten metal, of the refractory materialof which such piers are usually constructed.

One of the objects of the present invention is to oycrcome theobjections above pointed out, by providing,r a glass furnace in whichthe skew blocks and the furnace cap may be suspended over the tank orfurnace, and in operative relation thereto. A further object i's toprovide an improved suspension device for the skew blocks and cap of thefurnace. A further object is to protect the suspension devices from theintense heat to which they are normally subjected while in operation.v

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawings 'Figure 1 is a. sectional View, partly inelevation, illustrating a glass furnace constructed in accordance withthe invention. Fig. 2 is a horizontal sectional View on the line 2--2Fig. l. Fig. 3 is a vertical sectional View` on the line 3 3, Fig, l.Fig. 4 is an enlarged detail sectional View illustratin a skew block andthe suspension device. ig. 5 is a detail view of the brace struts forcarrying and supporting the suspended furnace cap.

Referring to the drawings, 10 designates a tank, the exterior Walls ofwhich may be constructed in :my well known manner and of any preferredmaterial, said furnace baving the drawing chamber 1l. Extending over thefurnace is a supporting frame comprising the upright bars or beams 12,positioned adjacent the corners of the furnace, and connected byvlongitudinal beams 13 and 14, secured to the upright beams in anypreferred manuel'. the -beams i3 boing above the beams 1 4. The beainsland 1l are connected by upright brace beams l5, and also by inclinedstrut hars 1G. By this arrangement it will be readily understood that anexceedingly rigid frame is provided, enh tending over the top of thefurnace, und capable of supporting a very heavy load.

Coperating with the supporting frame work, above described, is `asuspending frame, the same comprising transverse beams 17, resting uponand supported by the beams 13, and having secured thereto clcpendingg;beams 18, preferably arranged in pairs, said beams 18 being located onboth sides of the supporting frame. The beanss 17 are connected by strutbars 15). Extending lungivtudinally of the furnace, and secured to thedepending brains 18, are suspension beams 20, and secured to the lowerextremities of said depending 'beams 13. are L-sliaped beams 21. 'whichsupport the heel or skew 22, of thc furnace cap :23. Depend ing from thesuspension beams 20, are suslpension rods 24, the upper ends of saidrods einel passed through the beams 2U, and maintained in position bymeans of nuts 25. nr any other suitable moans. The lower ends of thesuspension rods "3l are threaded to engage supporting,- menibeij's 2G,shaped to enter a chamber 27 in the underside or bottom of the skewblock QS. By means of this arrangement the skew blocks 28, are supportedby the rods 24, which in turn are supported by the beam 20 attached tothe suspending frame, the heel or skew of the furnace cap beingsupported by the skew block, thereby maintaining the ce p of the furnacein its operative position. The suspending frame 1s braced at its lowerportion, by means of brace rods 29 connecting the bals 19, ing frame.

In practice, piers may be built up in the usual Way beneath the skewblock, but when at opposite sides of the suspendtile pien-i are noi usedit is neccwufy ilo pmteil't he Suplan'iiag members (5 from the ineusebeat oi' iiie inoiieu glam.

Itwill also be noted that the supporting device 2G is further protected bythe `biock 30. Any desired Pooling medium may be empioycd, but for thepurpose of iiilrzsi'aion Hw pipes 33 are shown ae provided with Supplyand diecbarge branchen Si and 35 respectively.
